The stuff doesn't really oxidize readily in air, though I do have some grayish fingerprints on mine. There's probably a skin of oxide, but I don't see
it disintegrating into carcinogenic powder anytime in the near future. Mine sits out on a shelf.
I wouldn't bother doing any chemistry with it. Then you risk making finely divided carcinogenic stuff...and the chemistry looks rather boring. Nothing
obvious with colors. The oxide is amphoteric and the halides are rather covalent, reacting pretty readily with water. About the only neat thing is the
basic acetate, which has a neat cage structure |
